To all whom it magl concern:

'Be it known that I, THOMAS L. TALIA- rnnuo, a citizen of the UnitedStates, re-

useful Improvements in Jar-Closures, of which the following is adescription, reference being had to the accompanying drawing and to thefigures of reference marked 10 th ereon. The invention relates to newand useful improvements in jar closures, and more particularly to a jarclosure having spaced lugs formed thereon adapted to engage screw ds orlugs on the jar for securing the closure to the jar.

An object of the invention is to provide a closure of the abovecharacter wherein the lower edge of theflange of the closure isstrengthened by infolding or bending the metal and wherein the lockinglugs or projections for securing the closure to the jar horizontallyindenting inwardly the strengthened lower edge so as to providevertically extending looking lugs or projections.

Fig. 2 is a bottom plan View of the same;

' ig. 3 is a view showing the blank With the depending flange and thelower edge rolled preliminary to the forming of the closure;

Fig. 4 is a View on the line H of Fig.

completed closure and the line 55 of a closure em- Fig. 5 is a similarview on of Fig. 1.

My improved closure for jars is made of metal and consists of a topportion 1 having a depending flange 2. his flange is rolled or bentinwardly as indicated at 3. The rolled or curled portion 3 is formed inthe first operation, made more or less open, and in the second operationis reduced to smaller proportions and the raw edge of the metalconcealed between the vertical portion of the flange and the part of theflange which is turned in. The flange is then subjected to furtheroperations which produce the curved outwardly projecting portion 4 whichis provided with knurls. This curved projecting portion lies between theupper and lower Specification of Letters Patent.

A jar closure comprising a top/portion having adepending flange with an outwardly projecting knurled curved portiondisposed between the upper and lower edges of the flange, said flangebeing rolled inwardly and flattened toconceal the raw edge of the metaland strengthen the lower ends of the flange, said flange within thelimits of the strengthened inturned edge being provided with spaced lugsformed by horizontally indenting the strengthened edge.
